python-requests 认证代理 httplib.BadStatusLine

通过 python-requests 进行身份验证的代理返回以下错误:

>>> import requests 
>>> proxies = {'https': 'http://username:password@proxy.company.com:8080',} 
>>> requests.get('https://api.github.com/',proxies=proxies,verify=False) 
Traceback (most recent call last):

requests.exceptions.ConnectionError: HTTPConnectionPool(host='proxy.company.com', port=8080): Max retries exceeded with url: https://api.github.com/ (Caused by <class 'httplib.BadStatusLine'>: ) 

经过身份验证的代理在 curl 中工作正常:

$ curl --proxy-user username:password --proxy http://proxy.company.com:8080 -k https://api.github.com/

如何排除故障？

请您参考如下方法:

Requests 从 2.0 开始就支持 HTTP 代理:https://github.com/kennethreitz/requests/pull/1515

顺便说一句，它确实尊重代理环境变量，所以你可以设置:

export http_proxy="http://username:password@proxy.company.com:8080" 
export https_proxy=$http_proxy
